Nvidia continues to introduce new graphics chips —?rom its Kepler lineup and after the top models are all already on the market it is time to also fill up the middle and lower range of products, and here comes the GeForce GTX 650 Ti. Not too long ago the company has introduced the 660 Ti and it instantly became my minimum must have GPU for gaming in stereo 3D mode at Full HD resolution, so the big question now is where the 650 Ti should be situated. Nvidia positions the GTX 650 Ti as a card for gamers with more limited budget that want to be able to play at 1920√?1080 or 1920√?1200 resolution with medium to high graphics details, but without pushing for the maximum ultra details and going for high AA settings. And if that is true for 2D gaming, then you should not expect the card to be able to perform great at Full HD resolution in stereoscopic 3D mode, sure you should still be able to play in that resolution, but you'll have to go for lower detail levels. So instead of trying to push the GTX 650 Ti to the limits at 1080p resolution in stereo 3D mode I've decided to test how good the card will perform in 720p resolution in stereo 3D mode. I have the feeling this graphic processor would be a great choice for stereoscopic 3D gamers that are using 3D projectors or 3D HDTVs to play games in 3D mode and there 720p is the typical resolution. Of course the goal would be 720p resolution with some AA and the maximum detail levels, so that the player would not be bothered by the lower resolution being used. But before doing some tests let us see what are the specifications of the GeForce GTX 650 Ti‚?¶
Specifications of GeForce GTX 650 Ti:
CUDA Cores ' 768 +576* The numbers in red and green represent the upgrade or downgrade of the specific parameter in the GTX 550 Ti as compared to the GTX 550 1GB!
Graphics Clock ' 925 MHz +25
Texture Fill Rate ' 59.2 GigaTexels/sec +30.4
Standard Memory Configuration ' 1024 MB GDDR5
Memory Interface Width ' 128-bit -64
Memory Clock ' 2700 MHz (5400 MHz effective) +650 (1300)
Memory Bandwidth ' 86.4 GB/sec -12
Texture Units (TMU) ' 64 +32
Raster Operator Units (ROP) ' 16 -8
Power connectors ' 1x 6-pin PEG
Power consumption ' 110W TDP -6
GPU Thermal Threshold ' 98 degrees Celsius -2
So the GeForce GTX 650 Ti is in overall a good successor for the GTX 550 Ti in terms of specifications and it should be offering a good performance increase as well, though according to Nvidia the people that should upgrade their GPU to the 650 Ti are probably the ones that are still using cards such as GeForce 9600 GT. And when talking about the competition, the GTX 650 Ti should be fighting with AMD's Radeon HD 7770, but this goes as far as playing games in 2D, so what about stereoscopic 3D gaming?
The benchmark results above were achieved on a mid-range computer ' MSI P55 motherboard, Intel Core i5 750 processor, 4GB RAM and Windows 7 64-bit, together with a reference GTX 650 Ti graphics card all of which were not overclocked. They games were ran at 1280√?720 resolution in stereoscopic 3D mode with no AA, but the good thing about us–łng AA filtering at 720p resolution is that it is really not as taxing as on 1080p resolution in terms of performance. So activating 4xAA in most games like the ones listed in the table only brings down the average FPS with something like 3-5 frames, and using 2xAA or 4xAA can really help in improving the visual quality at that resolution. So as expected, the GeForce GTX 650 Ti is a great card for more budget oriented stereoscopic 3D gamers that want to be able to play in stereo 3D mode on their 3D HDTV or 3D-capable projector at 720p resolution. If you want to be able to enjoy games in stereoscopic 3D mode on a 3D monitor at 1080p resolution you should consider going at least for GeForce GTX 660 Ti in order to get a good experience. On the other hand the GeForce GTX 650 Ti does perform quite well in Full HD resolution in most games if you don't want to play them in stereoscopic 3D mode, and you can do that as well on a 3D HDTV, though with a 3D projector not all models that support 720p 3D mode do support 1080p in 2D as well.
So in the end the GeForce GTX 650 Ti is a nice card that you can get for $159 USD and be able to get good experience playing in 1080p in 2D mode or 720p in stereoscopic 3D mode. The card is small, does not consume a lot of energy, the cooling is silent and at the same time you get good performance out of it ' a perfect combination for the not so demanding gamers or the ones with a more limited budget that cannot afford or just don't need to buy the top models. Well done Nvidia.
